FIRE A RCH.

Application led August cof/were.' I', HERMAN A. Porrenof the United States, re-

siding at Hammond, in the county of Lake Ahave invented new and useful Improvements in Fire Arches, of which the following is a specification.

This invention relates to and more vparticularly to firefurnaces arches which are made of bricks arranged in rows extending tiles or fire-arches for a plurality of from the front to the inner end of the arch and suspended from afiamework or superstructure above the same. f

One object of my invention is to provide an adjustable means for supporting the tiles at the inner ends of the rows -so that said tiles may be brought into proper contact with the next adjacent tiles to the rear regardless of yexist in tjhe n thus avoid providing gaps between any variation that may thickness of said tiles, and the tiles at the inner ends of the rows through which y cold air may be above the arch into t-herebelow.

A further obj drawn downward from the combustion chamber ect of my 4invention is to support the adjustable Atiles 1in a manner that Vnone of the thereabove is on the same,

weight of' the wall structurey andy thus enable saidV 'tiles to be readily' removed without tearing down or otherwise disturbing saidwall structu The invention consists further inthe matters'hereinafter described and more particularly set forth in the appended claims.

In the accompanying drawings- Fig. 1 is a lperspective view of one-half of Va` fire-,arch structure embodying the features of my invention;

,Fig 2 is .view taken through an enlarged vertical sectional the inner end of a row A.of tilesA and the wall structure above the same and showing the adjustable tile and .the structure for' suspending the same Fig. 3 is a front elevational view of yone structure therefor le tiles v,and showing the supa sectional view 2, and a top plan .view

blocks l, 1 arranged in rows extending at an inclination .upward .and inward from the front wall of the furnace setting, as customary in arches of .this general Acharacter. As shown in Figsl and 2, ythe tiles 1, 1 .iii each row rest or bear fiatwise vagainst each other throughout .their front and rear vertical faces. Also .the tiles 1 of one row contact along theirsideedgesvwith the tiles in the adjacent '.rows. In .the arch structure shown in Fig. 1, .there 'is Ya tile or brick 1a at the end of each row adjacent the front wall of the furnace, ,and this `tile a extends downward below the under or heat radiatingsurface of `the remainder of the tiles in the row, to .provide a step in the arch at said front wall to prevent ,cold air drawn Vinto the combustion Ycham-ber .through vthe inlet opening for the fuel ,from following and chilling said arch surface, as 'disclosed in the copending application of Thomas A. MarshfSerial No. 258,845 and filed .October 19, 1918.

Above the arch .are Lbeams 2, laterally spaced apart and extending from the front to the inner or rear end fof the arch structure. These beams 2 kare located between t'he rows of tiles 1 and have their base ange's 2a in channelsor grooves in the Sides of the adjacent tiles' for suspending .the same from said beams.v vExtending `transversely across the areh ,above the vbeams 2, 2 are crossgirders or channel members 3, 3, also spaced aparty and supported at their ends y in .the sideA walls of Athe furnace'setting. Engaged with .the lower flanges of these girders are hook-shaped members 41, 4, which embrace .the headed upper edges of .the beams 2 and support ,the cross-members 3, as' shown in Fig. 1.

Vhile the tiles 1 have substantially .the saine dimensions, yet `said Atiles vary yin thickness sufficiently to cause the tiles' 1 ,at the inner ends of theseveral rows to be out of alignment, transversely, as shown "Ein Fig. 4:. To compl-ete each row, there is a tile or block 5 at the inner end thereof, and it is essential that this tile 5 rest or contact Vflatwise throughout its innerQ vertical face with the adjacent face of the tile 1 next behind the same, in order to prevent a gap or space being formed between such .tiles and thus prevent cold lair being drawn through the arch yfrom above into and :beams from ksaid chilling the combustion chamber therebelow. To accomplish this object, I provide the following construction.

As illustrated in Fig. Il, the inner ends of the I-beams 2 all terminate in the same vertical plane. Extending across the spaces between the I-beams 2 at the inner ends thereof are flat plates 6. These are supported by said beams 2 in a manner permitting the plates 6 to be slid-or adjusted endwise of said beams for the purpose to be presently described. The form of connection shown consists of a flat flange 7 along the margin of the plate at one side and an upwardly offset flat flange Son the opposite side of the plate. The flange 7 rests or bears on the upper edge of one I-beam 2, and the offset flange 8 rests on the like edge of the opposite I-beam 2 by overlapping the flange 7 of the plate 6 supported in part by said beam, as shown in Fig. 3. Each plate 6 at its side edge provided 'with the offset flange 8 is also provided with a lower flange 9 engaging under the headed upper edge of the associated I-beam 2.

There is a plate 6 for each of the end tiles 5, and each is suspended from its plate 6 by a member 10 arranged in front of its plate 6. The member 10 is provided at its upper end with a pair of depending lugs 1l, 11, spaced laterally apart and adapted to engage be` hind upwardly projecting flanges 12 on the outer edge of the plate. These flanges 12, 12 terminate short of each other and provide slots or spaces 13, 18 allowing the member 10 to be engaged with its plate 6 by passing the lugs 11 inward between the flanges 12 and then sliding the member 10 to one side in a direction to position the lugs 11 back of said flanges 12. To remove the member 10 from its plate 6, the member is moved laterally in the opposite direction to register the lugs 11 with said slots 13 and withdrawing the member 10 outward from said plate.

The member l0 is provided at its lower end with a hook-shaped flange 14 projecting outward and disposed to enter a groove 15 in the rear face of the tile or block 5, as

j shown in Fig. 2. This suspends the tile 5 from its member'lO.

The members 10 being slidably mounted on the `Ibeams 2, said members, in building or erecting the arch in a furnace, may be adjusted endwise of said beams'to position and support the end tiles 5 in proper contact with the tiles 1 immediately to the rear thereof, regardless of any variations that may eXist in the tiles 1 in each row, as shown in Fig 4. Thus proper joints may be had between the tiles 5 and the tiles 1 next behind the same,

. and prevent spaces being formed to allow cold air to be drawn into the combustion chamber through the arch at Such points.

To complete the arch structure, a wall 16 is built above the tiles 5 at the inner end of the arch. This wall 16 is erected after the tiles l and5 have been placed in position and suspended from the I-beams 2. The wall 16 is built on the plates 6 after they have been adjusted for the purpose mentioned, and they vserve to support said wall. None of the weight of the wall 16 is on said end tiles 5. After said wall 16 is erected, the space between the bottom of said wall and the tops of the tiles 5 is filled with brick 17, which is the only part of said wall 16 which need be cut away when a tile 5 isto be released for repair or otherwise. After removing the section 17, the tile 5 may be removed by lifting it off the hooked end of its member 10 and withdrawing the tile outward from the member 10. Each plate has an upwardly projecting end flange 18 engaging said wall 16 at the rear thereof as an aid in supporting the same. Said plate 6 is also provided with a depending' flange 19 adjacent its rear or inner end. This flange extends between and engages the I-beams 2 between which the plate is located to position the plate and guide it in its adjustment.

The tiles 1a are suspended from the I- beams 2 by adapter plates 1b in the same manner as described in said copending application filed by Thomas A'. Marsh.

While I have shown and described herein in detail a lire-arch structure embodying the features of my invention, it is to be of course understood that the details of construction and arrangement of parts illustrated may be variously'changed and modified without departing from the spirit and scope of my invention.

I claim as my invention :v
